| 摘 要： | 自动发电控制(AGC)是电网自动控制的一项基本要求,电网对供电的较高要求需通过AGC和一次调频控制来实现。超临界直流炉机组蓄热能力小、初始响应速度慢,在AGC控制方式下常常难以满足电网的控制要求。针对浙能乐清发电厂超临界机组的特点,对机组协调控制系统进行分析,提出了控制策略优化和完善的措施。现场实际应用表明,改进后的协调控制系统控制策略能有效提高机组的负荷响应能力,且使机组运行更加稳定。

| Abstract: | AGC is a basic demand of the grid automation control. The high demands for power supply is accomplished by AGC and the frequency regulation. But the supercritical unit has the characteristics of slow speed to response and unable to store much energy, it makes the supercritical unit under the AGC mode can not meet the good power control requirements. Based on this characteristics of the Yueqing power plant supercritical unit, This pager analyzes the CCS, gives some steps to refine and improve the control strategy. The practice presents that the refined system control strategy can improve the ability to response to the unit loads, meanwhile makes the unit run more stably. |
